RESUMO
INTRODUCTION: Infants with single ventricle following stage I palliation are at risk for poor nutrition and growth failure. We hypothesise a standardised enteral feeding protocol for these infants that will result in a more rapid attainment of nutritional goals without an increased incidence of gastrointestinal co-morbidities. MATERIALS AND METHODS: Single-centre cardiac ICU, prospective case series with historical comparisons. Feeding cohort consisted of consecutive patients with a single ventricle admitted to cardiac ICU over 18 months following stage I palliation (n = 33). Data were compared with a control cohort and admitted to the cardiac ICU over 18 months before feeding protocol implementation (n = 30). Feeding protocol patients were randomised: (1) protocol with cerebro-somatic near-infrared spectroscopy feeding advancement criteria (n = 17) or (2) protocol without cerebro-somatic near-infrared spectroscopy feeding advancement criteria (n = 16). RESULTS: Median time to achieve goal enteral volume was significantly higher in the control compared to feeding cohort. There were no significant differences in enteral feeds being held for feeding intolerance or necrotising enterocolitis between cohorts. Feeding cohort had significant improvements in discharge nutritional status (weight, difference admit to discharge weight, weight-for-age z score, volume, and caloric enteral nutrition) and late mortality compared to the control cohort. No infants in the feeding group with cerebro-somatic near-infrared spectroscopy developed necrotising enterocolitis versus 4/16 (25%) in the feeding cohort without cerebro-somatic near-infrared spectroscopy (p = 0.04). CONCLUSIONS: A feeding protocol is a safe and effective means of initiating and advancing enteral nutrition in infants following stage I palliation and resulted in improved nutrition delivery, weight gain, and nourishment status at discharge without increased incidence of gastrointestinal co-morbidities.

BACKGROUND: Despite limited recommendations for using sodium bicarbonate (SB) during cardiopulmonary resuscitation (CPR), we hypothesized that SB continues to be used frequently during pediatric in-hospital cardiac arrest (IHCA) and that its use varies by hospital-specific, patient-specific, and event-specific characteristics. METHODS: We analyzed 3719 pediatric (<18 years) index pulseless CPR events from the American Heart Association Get With The Guidelines-Resuscitation database from 1/2000 to 9/2010. RESULTS: SB was used in 2536 (68%) of 3719 CPR events. Incidence of SB use between 2000 and 2005 vs. 2006 and 2010 was 71.1% vs. 66.2% (P=0.002). The primary outcome was survival to discharge. Secondary outcomes included 24-h survival and neurologic outcome. Multivariable logistic regression analyzed the association between SB use and outcomes. SB had increased use an ICU location, metabolic/electrolyte disturbance, prolonged CPR, pVT/VF, and concurrently with other pharmacologic interventions. Adjusting for confounding factors, SB use was associated with decreased 24-h survival (aOR 0.83, 95% CI: 0.69, 0.99) and decreased survival to discharge (aOR 0.80; 95% CI: 0.65, 0.97). Inclusion of metabolic/electrolyte abnormalities, hyperkalemia, and toxicologic abnormalities only (n=674), SB use was not associated with worse outcomes or unfavorable neurologic outcome. CONCLUSIONS: SB is used frequently during pediatric pulseless IHCA, yet there is a significant trend toward less routine use over the last decade. Because SB is more likely to be used in an ICU, with prolonged CPR, and concurrently with other pharmacologic interventions; its use during CPR may be associated with poor prognosis due to an association with "last ditch" efforts of resuscitation rather than causation.

BACKGROUND: Following the Norwood palliation, neonates may require an escalation of inotropic and vasoactive support. Arginine Vasopressin may be uniquely useful in supporting this population. MATERIALS AND METHODS: A retrospective evaluation of neonates at this institution between November, 2007 and October, 2010 who received Arginine Vasopressin following the Norwood procedure. Data were recorded from the patient records at one hour prior to, and then 1, 2, 3, 4, 6, and 24 hours following Arginine Vasopressin initiation. RESULTS: We included 28 neonates. The mean dose of Arginine Vasopressin was 0.0005 plus or minus 0.0003 units per kilogram per minute. There was an early response (less than 6 hours) characterised by an 8% increase in systolic blood pressure (p = 0.0004), a 100% increase in urine output (p = 0.02), and a 29% decrease in total fluid administration (p = 0.04). The late response (at 24 hours) revealed further increases in systolic blood pressure and urine output as well as a 53% decrease in serum lactate (p = 0.007) and increase in arterial pH from 7.36 to 7.45 (p less than 0.0001). These changes were not accompanied by increases in heart rate or inotrope score. CONCLUSIONS: The initiation of Arginine Vasopressin in post-operative Norwood patients was temporally associated with an improvement in markers of perfusion including systolic blood pressure, urine output, lactate, and pH. Further studies are required to ascertain the efficacy of Arginine Vasopressin in this population.
